Hi,
I have a 1997 Fleetwood Bounder, and it worked fine in 19F weather. I have not camped in 10F weather, but guess it will work fine.
What to look for?
Large fresh water tank is handy, because I could fill it once and then disconnect the fresh water hose, put it away until another sunny day to refill the tank again, and dump the grey and black tanks.
Tanks inside a basement storage compartment that typically has a heater air duct is normal these days. They will not freeze, and will keep working when you are keeping the RV warm inside, and using the systems.
Dual pane windows also slow the heat loss. Most RV's have them now, mainly because they are quieter than single pane windows.
I increased my battery capacity and installed solar panels, mainly because I do not like RV parks and campgrounds. I prefer to camp out in the woods out west, boondocking of sorts.
If you are taking about camping in -10F weather, good luck. Many RV's do not stand up to that low of temperature. Yet most will handle 10F without any problems.
Fred.
Money can't buy happiness but somehow it's more comfortable to cry in a
Porsche or Country Coach!
If there's a WILL, I want to be in it!
I havn't been everywhere, but it's on my list.
